Oh gosh, I know!!!! It seemed like an eternity before I got my first cats and then it was even longer still before they were ready to breed! But I wouldn't trade that time for anything in the world. I learned SO much in those 3 years that turned out to be very valuable information to me when the time came. I spent it wisely and read every book I could get my hands on, I talked to other breeders and people in the cat fancy about the illnesses and other issues with my chosen breed, I went to various cat-related events and shows and I spent a LOT of money ordering pedigrees and pedigree software to see which cats in what lines I wanted to cross!
I am excited for you with this being your first litter!! I am hoping to breed my two again just as soon as Lexus goes back into estrus. I don't know what she is waiting for though ... she had a litter on October 3rd of last year and while she has been in estrus a few times, I didn't feel she was quite ready for another litter so I waited. Now that I want her to come in, she won't. *grin*
